Shutdown issue about thinkpad-x1c5-hackintosh HOT 9 CLOSED

@marioeva Can you please dump your unpatched ACPI? I can try and take a look.

Hmm that's wierd. Are you using the same BIOS version as I do (1.45)? This is important as different BIOS versions can mess withe the ACPI patches. You could also try enabling verbose boot, so you see exactly where the shutdown gets stuck

thank you for the guide.

I just found that my BIOS is 1.46 and seems Lenovo only provide 1.48 version now and it requires Windows.

If I have to live with 1.46 BIOS, which ACPI should I amend?
I will try verbose boot and report back

ACPI is not really a field that I'm very familiar with. I mainly incorporate the patches done by @tylernguyen for the x1c6, after extensive testing. The machines are almost identical an he's way better at this stuff than I am. If he updates his BIOS I will push the changes here as well after I tested them.

However I'm afraid I can't really help you, as I lack the time and the knowledge to reallly dive into it

You are so nice, much appreciated.
Please see attached system report and EFI ( which is copied from here)

I did not replace the WiFi/Bluetooth card, used the original one and used appleintelwifi.kext. This is the only hardware difference

I diff your DSDT against mine and on first glance, it doesn't look much different and shouldn't cause any problems. Could you try removing/disabling your network card?

If that doesn't work, I suggest you start disabling kexts and acpi patches one by one until you figure out which may be causing that problem.

I used open core 0.59, all default setting, then copy your kext and apci. Now 80% of time the issue is fixed.. For remaining 20% of time, the machine reboots instead of shutdown.

Its not perfect but I can live with in

Thank you both again for the help

Make sure that your ACPI patches are loaded in the correct order.
You need to patch USB properly. It is likely that the x5 has a different usb mapping than the x6.
